<p>Calcium phosphate containing materials, e.g. apatite can be separated from contaminant materials, e.g. calcite and silicates, by a selective froth flotation process. This process uses a mixture of a class of amine oxides and a branched chain C16 to C20 fatty acid and provides a high usable concentration of the apatite with good separation from the gangue.</p> |
